does anyone know how to manually read fault codes in an au(2/3)?

my gas is still guzzling and i dont believe ultratune when they say they checked for fault codes...

cheers

for the record, im close to dumping the stock ecu.

Pretty sure your only option is to have ford read this with the WDS or whatever its called...

i.e. cant do the 'flashing LED' style diagnostics....

yes what hea said!

or some mechs have the snap on reader which do read the AU's
and i am led to belive the BA's as well


as for your gas drama take it to a LPG mech who knows what they are doing

Hi

find a local Launch agent in ur area and they will direct u to one of there mechanical workshops that have there scan tools it will cover you car and u also get a printout with this type of scan tool where others dont have that and no lies whether they have done a diagnoses on your car


i have the OTC4000 and the launch X431 great tool ( dedicted test equipment )

if you where in melbourne would gladly test it for you free of charge while you wait.

If you need more info private me and will give you more deatils

Have the vehicle run on a chassis dyno and have a High Speed airfuel ration meter log all the mixture settings on the dyno from light throttle cruise to wide open throttle (WOT) high load you will see straight away if the gas system is operating correctly

A/F ratio for gas is light throttle cruise 15.4 :1

wide open throttle between 12.5 to 13:1 depends on the system where you make max hp.

another option is go to techedge.com and buy your own air/fuel ratio meter and test things yourself if you want to save money have fun cya
